In Genesis 4, we see specific reference to herdsmen and farmers as distinct groups, represented by Abel and Cain, respectively. God indicates a preference for the results of herding over planting, and the sibling troubles that ensue result in the world becoming a difficult place to farm, and humans becoming more nomadic, as herders. […]

Genesis 2 ends with Adam and Eve being naked yet not ashamed. In Genesis 3, the Serpent, who is wiser than average, tricks Eve into partaking of the forbidden fruit of one of god’s two magic trees. This results in Adam and Eve recognizing their own nakedness, and compelling them to produce the […]

Genesis 1 and Genesis 2 (5 – 25) are distinctly different and contradictory origin stories. The biblical origin story represented in this text has long been known to resemble a set of Sumerian stories that mainly deal with a multitude of gods interacting (some of these gods are converted to humans in the […]

This installment is about sea level rise and fall, in the past. Sea level change that results from the formation and melting of glaciers not only has an enormous impact on the physical nature of the landscape, but it also would not have gone unnoticed by people living ever pretty far from the sea! […]

In the last post in this series (Global Warming, the Blog Epic ~ 05 ~ Causes of Large Scale Change) I talked about two aspects of large scale climate change: Milankovitch orbital geometry and the cycles of glaciation this effect causes, and the role of plate tectonics and related changes in altering sea and […]

As a child in Catholic school, and later in public school and being sent off to “release time” religious instruction, I had the opportunity to read most of the Old and New Testaments of the standard bible. Later, in junior high school, I became interested in comparative religion, and read it all again, together […]

“Climate Studies” is a “causal” science. Most sciences are “causal” in nature, which is why the sciences and scientists are often loathed and distrusted by people in the humanities and some of the soft sciences. There is not the time or space right now to address this issue, but I’ll just say this: […]

Why It Matters What you Burn and When you Burn It
Carbon Dioxide is a deadly poison. It is about 50% heavier than air, so where it occurs in density, in mines or certain natural vents associated with volcanics, it can accumulate in low spots. There are places in the Western Rift Valley where […]

Why Greenhouses have nothing to do with the Greenhouse Effect, and more importantly, why CAN’T I microwave toast?
A greenhouse is a glass house that is sealed to keep air in and insulated to keep heat in but at the same time allow sunlight in. This sunlight contributes to the heat in the greenhouse by […]
